94e9ac2125 Move iic.h to sys/ so that it's automatically installed in /usr/include/sys.
This lets us call iic(4) ioctls without needing the kernel source code
and follows the same model of GPIO.

96e0511f76 Initialize the switch vlan table at attachment.
Update some comments on code, specifying the correct vlans used on switch
setup.

Advertise the proper switch operation mode (the rtl8366rb only support
dot1q vlans).

This fixes the breakage that i introduced on r249752 and make the rtl8366rb
switch works again with etherswitchcfg(8).

Tested on TP-Link 1043ND.

e85950412d Set all of the ports into the same vlangroup; there's only one vlangroup
(pvid=1) and we already configure them to send to other ports.

Setting pvid=portnum would mean that there were separate vlangroups
for each ports, but 'leaking' into other ports.  The result? All port
traffic flooded to all other port traffic.

6ec7b630f8 Add ATU flush support.
The OpenWRT AR8xxx switch support flushes the ATU (address translation
unit) after each port link 'up' status change.  I've modified this to
just flush on any port transition.

Whilst here, bump the number of ports on the AR8327 to 6, rather than
the default of 5.  It's DB120 specific; I'll go and make this configurable
later.

There's some debugging code in here still; I am still debugging whether
this is or isn't working fully.

263a450392 (I think!) make the AR8327 switch correctly handle traffic.
This patch does four things:

* it globally disables mirroring;
* it globally sets the mirroring on each port to be disabled;
* the initial port setup now programs a portmask for the port to allow
  transmission (forwarding) to all other ports bar itself;
* the vlan setup path now programs the portmask for the port to
  allow transmission (forwarding) to all other ports bar itself.

Before this, I hard-coded the portmask to 0x3f which would mean all
ports (bar port 6, which currently isn't hooked up to anything.)
This means that traffic would be duplicated back out the port it
received it.  I bet this wasn't .. optimal.

In any case, this _seems_ to make DHCP from my macosx laptop
work through this access point.  I'll do some further testing
to ensure it's actually working correctly on all my devices.

4578386a6e Add in port0/port6 configuration as part of the platform data code path.
It's still hardcoded (for db120) but it is now hardcoded in all the

port0/port6 as appropriate to configure things.

14d0aacff0 Add initial AR8327 support.
This is (almost!) enough to actually probe, attach, configure a default
port group and do some basic work.  It's also totally hard-coded for
the Qualcomm Atheros DB120 board - it doesn't yet have any of the code
from OpenWRT which parses extra configuration data to know how to program
the switch.  The LED stuff is also missing.

But, it's enough to facilitate board, PHY, switch and VLAN bringup,
so I am committing it now.

51961034e3 Methodize the arswitch VLAN routines.
These differ per chipset family in subtle and evil ways.

It becomes very noticable on the AR8327 where the layout is just plain
wrong.

05b5deca74 * Ensure enough ports/phys are available for both the AR8327 and previous
switches.

* Add some new VLAN HAL methods that will be used by the VLAN configuration
  code.  The AR933x and later switches use slightly different register
  layouts (even though the driver currently doesn't support it.)

44c01df173 Fix undefined behavior: (1 << 31) is not defined as 1 is an int and this
shifts into the sign bit.  Instead use (1U << 31) which gets the
expected result.

This fix is not ideal as it assumes a 32 bit int, but does fix the issue
for most cases.

A similar change was made in OpenBSD.

* Add an AR9340 switch version entry;
* Support the switch being connected via MII;
* Add a flag to note that a switch is actually an internal
  switch rather than an external switch.

Now:

* The ar9340 switch can interconnect via MII;
* Since some slightly different phy/switch register access methods
  and quirks appear for the internal versus external switch,
  we will need a flag to mark it as an "internal" switch.
